黄瓜嫁接就是用南瓜根替代黄瓜根的栽培技术。由于南瓜根系发达,对低温、高温的适应性强,不易受土壤传染病的感染,对多种病害都有预防效果,特别是能根治枯萎病,此病在连茬3年的温室、大棚中发病率高的可达50%左右,不能再继续栽培黄瓜。嫁接后的黄瓜还具有显著的早熟高产特性。随着保护地蔬菜栽培的迅速发展,黄瓜嫁接技术日趋成熟,达到实用推广程度,得到广泛的应用和重视,成为一项抗病增产的有力措施。目前,亩产达1—2万公斤,产值2—3万元的高产典型,几乎都采用了嫁接技术。一、南瓜品种选择与种子处理品种以黑籽南瓜为佳,每公斤约4400粒,亩用量1.2公斤。当年新种子休眠期长,发芽率低,故应选用隔年种子。如用当年新种子就必须采用下述方法打破休眠。
Cucumber grafting is the use of pumpkin root instead of cucumber cultivation techniques. As pumpkin roots developed, adaptable to low temperature and high temperature, not susceptible to infection of soil-borne diseases, have a preventive effect on a variety of diseases, especially to cure blight, the disease in the continuous 3-year greenhouse, greenhouse High incidence of up to 50%, can no longer continue to cultivate cucumber. Grafted cucumber also has significant early maturity and high yield characteristics. With the rapid development of protected vegetable cultivation, cucumber grafting technology has matured to a practical degree of promotion, which has been widely used and valued, becoming a powerful measure to increase disease resistance. At present, the mu production of 1-2000 kg, the output value of 2-3 million high-yield typical, almost all used grafting technology. First, the choice of pumpkin varieties and seed treatment varieties of black pumpkin is better, about 4400 kilograms per kilogram, the amount of 1.2 kilograms of mu. When the new seed dormancy period is long, germination rate is low, it should be used for the next year seeds. If you use the new seed that year must be used to break dormancy.
